Why Cannabis Brands Choose Custom Over Stock Mylar Bags

When you’re competing in a saturated market, packaging becomes more than just a container; it’s a tool for compliance, branding, and customer trust.

That’s why more cannabis brands are investing in fully custom Mylar bags built for their product and audience.

Here’s what makes custom packaging a smart move.

Compliance Isn’t Optional, Custom Makes It Easier

You need to meet strict state laws, and custom Mylar Bags make it seamless to include all required features and labeling.

Prioritize:

  • Child-resistant zippers to meet legal packaging standards
  • Tamper-evident seals for secure, compliant presentation
  • Space for dosing, warning labels, and THC content without clutter

Pro tip: Designing from scratch lets you bake in compliance instead of squeezing it in later.

Shelf Appeal Starts With Smart Design

When your bag looks high-end, people assume what’s inside is too. It’s an instant brand elevation.

Look for:

  • Premium finishes like matte, metallic, or holographic
  • Window cutouts or shaped die-cuts for added visual interest

Want your logo to pop at first glance? Consider full-panel printing with bold contrast; it’s a favorite among pre-roll brands

Pro tip: A premium look isn’t just pretty; it gives you pricing power.

Custom = Functional Packaging That Fits Your Product

You’ve spent time perfecting your product. Don’t settle for packaging that’s just “close enough.”

Choose:

  • Right-sized formats like 3.5g, 7g, or single-serving edibles
  • Odor-proof barrier layers for discretion and freshness
  • Heat-seal or resealable closures to suit the product’s shelf life

What seasoned brands know: Better fit = better shelf life and shelf appeal.

Branding That Works Overtime

Great packaging creates brand recognition, trust, and repeat sales.

Here’s why it matters:

  • Increases brand recall by up to 30% vs. stock packaging
  • Helps products get picked first in crowded dispensary displays
  • Gives customers a consistent, professional impression

Pro tip: People judge packaging in under 7 seconds, so make sure the first impression counts.

Popular Sizes: What Are 3.5 Mylar Bags?

In the cannabis world, 3.5 Mylar bags are one of the most in-demand packaging formats.

Average dimensions for 3.5 bags:

  • Typically range from 4″ x 6″ to 5″ x 8″
  • Can be flat, gusseted, or stand-up
  • Perfect for shelf displays or vertical hanging

Why cannabis brands love 3.5 bags:

  • Ideal for single-serve packaging
  • Cost-effective for high-volume production
  • Easy to customize with branding + compliance details
  • Fits well in retail displays and behind dispensary counters
  • Familiar format that builds consumer trust

And because they’re such a staple, custom 3.5 bags are an easy way to upgrade your look without changing your entire packaging system. Add a matte finish, metallic accents, or custom die-cuts, and suddenly your product pops.

2. Are all 3.5 Mylar bags the same size?

No. While “3.5” refers to capacity (⅛ oz or ~3.5 grams), actual bag dimensions vary slightly depending on gusset, seal style, and bag format. At Beast Coast, we offer tailored sizing for a perfect fit.

Mylar bags are great for:

  • Cannabis flower (most common use)
  • Edibles (gummies, baked goods, mints)
  • Concentrates (inside an inner container)
  • Pre-rolls or multipacks
  • Samples or promotional giveaways

6. Are Mylar bags smell-proof?

7. How long do Mylar bags keep cannabis fresh?

When properly sealed, Mylar bags can preserve cannabis flower for several months by protecting against moisture, oxygen, UV light, and odor leakage. The multi-layer barrier helps maintain terpene and cannabinoid integrity, crucial for shelf life and consumer satisfaction.
